Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Cardiac Imaging Surveillance
Regular echocardiography and cardiac MRI to monitor cardiac function, assess shunt physiology, and detect any progressive changes requiring intervention.
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Surgical Repair
Corrective surgical intervention to restore normal atrial anatomy and address associated defects. The specific procedure depends on the exact anatomy and associated abnormalities.
Additional treatment options
Anticoagulation Therapy
Blood thinning medications to reduce thromboembolic risk associated with abnormal atrial geometry and potential stasis. May be long-term depending on individual risk assessment.
medicationActivity Restrictions and Cardiac Rehabilitation
Guided physical activity modifications and structured cardiac rehabilitation program to maintain cardiovascular fitness while avoiding excessive cardiac stress.
lifestyleDiagnostic Cardiac Catheterization
Invasive catheterization procedure to obtain detailed hemodynamic measurements, assess defect characteristics, and guide surgical planning when non-invasive imaging is insufficient.
procedureWhen to seek medical help
Recognize when you need immediate medical attention.
